Notes. TTO is the total time observed. Calibrator diameters (mas): ϵ Ser = 0.689 ± 0.048 (1); 72 Oph = 0.684 ± 0.048 (2); λ Aql = 0.518 ± 0.036 (2); ι Cyg = 0.586 ± 0.041 (2); HR 8185 = 1.067 ± 0.076 (2); γ Lyr = 0.737 ± 0.015 (3); 17 Cyg = 0.721 ± 0.051 (2); σ Cyg = 0.542 ± 0.021 (4). All the diameters, except for ϵ Ser, are in the H band. ϵ Ser is given in K band, variation across wavelength for this diameter is extimated to be ~0.01 mas with negligible effect on the data reduction.
